The Benefits of Insulation

Insulation works by radiating heat energy back into the building, helping your home stay warmer for longer and requiring less energy to heat. Good quality, properly installed insulation will ensure your home remains comfortable in all New Zealand conditions.

How it works

The Benefits of Ceiling Insulation

It is estimated that 40% of heat is lost through an insulated ceiling.

Maintaining good levels of ceiling insulation in your roof cavity is regarded as the single most important way to ensure you have a warm, dry, healthy and energy efficient home. During winter, ceiling insulation improves your homes ability to retain heat, meaning a warmer home and lower heating bills. During summer, ceiling insulation restricts the excessive heat in your roof cavity from radiating down into your home, meaning a more comfortable living environment and reduced cooling bills. 

The Benefits of Underfloor Insulation​

It is estimated that over 1 million homes in New Zealand have little or no underfloor insulation, and poorly installed insulation is responsible for over 10% of heat lost through the floor. An average sized underfloor allows 40 litres* of moisture to be uplifted into the home every 24 hours. Installing underfloor installation is a cost-effective solution to preventing heat loss, reducing dampness and creating a warm, healthy home.

*Rising moisture is calculated at 0.4L of water per m2 of floor area per day.  

Insulation

Ceiling

To comply with NZ Regulations, Landlords and Property Managers must ensure that their rental properties are fitted with both ceiling and underfloor insulation.

The healthy home standards became law on 1 July 2019. The healthy home standards require specific and minimum standards for heating, insulation, ventilation, moisture ingress and drainage, and draught stopping in rental properties.

Landlords and property managers are responsible for maintaining and improving the quality of their rental properties.

Wall Insulation

Wall insulation Once you’ve insulated your ceiling and underfloor, installing wall insulation is the next most effective step for reducing heat loss in your home. It’s difficult to check and install wall insulation in existing houses without taking the lining or cladding off, so if you’re renovating take the opportunity to do it.
